PLOW.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed May 8.1906. Serial No. 315,797.

To (LZZ whom, it may concern.-

Be it known that I, BRUCE NUNNALLY, a citizen of the United States, residing at Jacksonville, in the county of Cherokee and State for holding one or more plow-standards or.

harrow-teeth.

Another object is to provide a beam, to which notched devices, such as plow-standards or harrow-teeth, maybe connected, so as to be capable of lateral or vertical adjustment.

WVith the above and other objects in view the invention consists of a beam having parallel cross-strips extending above and below it, and these strips are adapted to project into notched devices, such as teeth or plowstandards, and means are provided whereby these devices can be securely clamped upon the cross-strips and in any positions to which they may be adjusted.

The invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

vation.

In the accompanying drawings is shown the preferred. form of the invention.

In said drawings, Figure 1 is a side eleva- Fig. 2 is a plan view showing by dotted lines the manner of adjusting the cross-strips. Fig. 3 is a detail view of a'plowstandard. Fig. 4 is a similar view of a back plate, and Fig. 5 is a detail view of a harrowtooth.

Referring to the figures by characters of reference, 1 is a beam of any suitable proportions having handles 2 connected to its rear end. Secured to the upper and lower faces of the beam adjacent the handles are parallel cross-strips 3, said strips being fastened, preferably at their centers, to the beam by means of a bolt 4. Connecting-pins 5 are fastened to the ends of the cross-strips, and secured to these pins are brace-rods 6, which are fastened to the sides of the beam and serve to hold the cross-strips against movement. If the beam is to be used for plowing purposes, a plowstandard may be fastened to the cross-strips 3 at each side of the beam. The standards 7 used in connection with the strips have longitudinal]y-extending slots 8 therein, and notches 9 are formed in the rear faces thereof and are adapted to receive the front edges of cross-strips 3. A back plate 10 bears upon the opposite edges of the crossstrips and has an enlargement 11, which fits snugly between the strips and prevents the back strip from rotating. A bolt 12 we tends through each of these back strips and. through the slot in one of the plow-standards and is fastened therein by means of a nut 13 or in any other preferred manner. Obviously by tightening this nut the plow-standard will be clamped upon the front edges of the cross-strips, and by loosening the nut said standard can be adjusted vertically or can be moved from or toward the plowbeam, after which it can be resecured.

Instead of using plow-standards harrowteeth 14 may be employed, each tooth having notches 15 to receive the front edges of the cross-strips and also having a back plate 10, to which it is connected by a bolt 12. Any desired number of these harrow-teet-h may be arranged at each side of the beam, and said teeth can be readily secured in desired positions in the manner described. If it is desired to use the beam in connection with a single plow-standard, the two crossstrips 13 can be removed by withdrawing the bolt 4 and detaching the brace-rod 6, and a standard can then be connected to a beam in the ordinary manner.

The implement herein described will be found to be of considerable utility in that it can be used either as a single or double plow or as a harrow. It can be manufactured at slight cost, and in view of the manner in which the notched faces are connected to it the same can be adjusted to suit various conditions.

The preferred form of the invention has been set forth in the foregoing description; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the invention.

What is claimed is 1. In an agricultural implement of the character described the combination with a beam; of parallel cross-strips secured to opposite faces thereof and each having a straight uninterrupted edge, an element having notches therein adapted to receive the straight edges of the cross-strips, a back plate slidably mounted on the opposite edgeqof said strips, and means connecting said plate and the notched element for clamping the plate and element upon opposite edges of the strips, said plate and element being slidable longitudinally of the strips.

2. In an agricultural implement of the character described the combination With a beam; of parallel cross-strips connected to opposite faces of the beam, each strip having a straight uninterrupted edge, an element having a curved face provided With notches adapted to receive the straight edges of the strips, a back plate slidably engaging the
